NAME

     gtp -- Gemtek PCI FM radio device


SYNOPSIS

     gtp*   at pci? flags 0x00
     radio* at gtp?


DESCRIPTION

     The gtp driver provides support for the Gemtek PCI and Guillemot MaxiRa-
     dio FM2000 FM radio tuners.

     The Gemtek PCI cards are stereo FM tuners that can tune in the range 87.5
     - 108.0 MHz, report signal status and stereo/mono on the current fre-
     quency, force audio output to mono, perform hardware signal search, and
     have an internal AFC.

     The card is based on the TEA5757 chip; see radio(4) for details.

     The flags control the driver behavior.  For example, with flags 0x01 the
     driver will assume that a TEA5759 chip is used.

HISTORY

     The gtp device driver appeared in OpenBSD 3.2 and subsequently in
     NetBSD 1.6 wherein it replaced the mr(4) driver.


AUTHORS

     The gtp driver and the man page was written by Vladimir Popov
     <jumbo@narod.ru>.


BUGS

     It is impossible to determine which frequency the card is tuned to.
     Thus, the driver will report an internally stored value even if it is not
     correct (changed by some program that uses direct port access).
